Note:
• Initial charging: Charge the batteries for at least 16 hours, re-
gardless of the charging status icon. Without replacing it in the
charging shell, use the handset until the "battery low" beep is
heard. This action aligns the charge status display with the op-
erating times of the batteries.
• To attain full operating and charging times (Æ page 15): With-
out replacing it in the charging shell, use the handset until the
"battery low" beep is heard.
• For future charging: you can place your handset in the charging
shell each time it is used. Charging is electronically controlled
which ensures that the batteries are charged optimally.
